From 599b0bf438e387dbaf00dbadcbe41b2a0de90db1 Mon Sep 17 00:00:00 2001 From: Erik Faye-Lund Date: Tue, 23 Nov 2010 19:38:24 +0100 Subject: [PATCH] msvc: opendir: fix malloc-failure Previsouly, the code checked for malloc-failure after it had accessed the returned pointer. Move the check a bit earlier to avoid segfault.
